Thermophysical and Transport Properties of Metals at High Pressure and Very High Temperature

Abstract

High pressures are usually applied to investigate the properties of materials at higher than normal density, i.e., higher than found at room temperature and one atmosphere. Pressure can also be used to elevate the boiling temperature and thereby stabilize the liquid phase at densities several times less than normal. We have recently described the use of such a technique to obtain equation of state and transport data for liquid metals up to 0.4 GPa, 7000 K, and two- to fourfold expanded [1,2]. Such information is necessary, for example, for accurate predictions of release processes following shock loading, intense laser pulse absorption, or any other rapid energy deposition.
